Help Ruger MK3 Disassembly!!!

Alright guys I bought a Ruger MK3 and shot it today, it performed really well but I like to disassemble all my firearms and clean them after range trips...but I'll never take this damn thing down again.

I've got a problem. Alright I took out the mainspring assembly, pulled the trigger to remove the bolt, and the damn magazine won't release. Just to clarify, I removed the bolt and the magazine simply won't come out of the gun. The release button is unresponsive.

What do I do? I just can't figure it out. The magazine simply won't release from the gun and it is stuck. :cuss: :banghead:
